VIII. Button Operation
Power button
●
Long press power button for more than 2 seconds to turn on the tester (full symbols
are displayed on LCD for 1 second), long press again to turn it off. The tester is
designed with auto power off function.
● IR
Insulation resistance testing button: The default mode is continuous insulation
resistance testing mode when powering on the tester. Short press this button to
switch to insulation resistance testing function.
● V
AC/DC voltage testing button: Without high voltage output, short press "V" button
to switch to AC/DC voltage testing mode. The tester can identify AC/DC voltage
automatically (UT513C).
For UT513B, please select DCV or ACV button manually to enter corresponding
DC or AC voltage measurement mode.

Capacitance measurement button: Without high voltage output, short press "
to switch to capacitance measurement mode.
● ▲
A. Under insulation resistance measurement or capacitance measurement
condition and without testing voltage output, short press ▲ to select high-range
voltage output.
B. For data reading, press ▲ to select last group of data.
C. For time or resistance setting, press ▲ to increase time or resistance.
● ▼
A. Under insulation resistance measurement or capacitance measurement
condition and without testing voltage output, short press ▼ to select low-range
voltage output.
B. For data reading, press ▼ to select next group of data.

A. Under insulation resistance measurement condition and without testing voltage
output, press
to progressively increase at the step of corresponding range
(increase by 120% at a step of 10% each).
B. For time or resistance setting,
button is used as a cursor button to adjust time
and resistance.
C. After polarization index or absorption ratio measurement is completed, press
cyclically display polarization index or absorption ratio, insulation resistance in
Time2 and Time1.
READ
●
Without high voltage output, short press "READ" to read latest group of saved data,
and press ▲ and ▼ to select different data.
SAVE
●
Short press "SAVE" to save current displayed data. The LCD shows the symbol "FUL"
and the number of group "999" to indicate full storage. To save next group of data,
please clear the saved data.
Backlight button
●
